Functions of the Heart/Lung
The heart is a strong and muscular, cone-shaped organ that is about the size of a fist. It pumps blood throughout the body and is located behind the breastbone between the lungs. Deoxygenated blood flows from the heart to the lungs where it gives up wastes and is freshly oxygenated. From there, the blood returns to the heart and is pumped to the rest of the body. Heart failure is the inability of the heart to pump enough blood to maintain normal body requirements. Birth defects or any condition that damages or overloads the heart muscle can cause it. Treatment depends on the cause of heart failure and the age and condition of the patient.
Lungs are a pair of highly elastic and spongy organs in the chest. They are the main organs involved in breathing. They take in air from the atmosphere and provide a place for oxygen to enter the blood and for carbon dioxide to leave the blood. The lungs are divided into lobes, with three on the right and two on the left.
Heart/Lung Transplant Procedures
Heart/lung transplants generally involve the transplantation of two lungs with the heart. There have been very few heart/lung transplants performed using only one lung.
